Police in the UK are planning to use unmanned spy drones, controversially deployed in Afghanistan, for the ­”routine” monitoring of antisocial motorists, ­protesters, agricultural thieves and fly-tippers, in a significant expansion of covert state surveillance.

The arms manufacturer BAE Systems, which produces a range of unmanned aerial vehicles (UAVs) for war zones, is adapting the military-style planes for a consortium of government agencies led by Kent police.

Documents from the South Coast Partnership, a Home Office-backed project in which Kent police and others are developing a national drone plan with BAE, have been obtained by the Guardian under the Freedom of Information Act.
